2010-02-05Fix bug 7104 - "wide links" and "unix extensions" are incompatible.Jeremy Allison1-1/+1
Change parameter "wide links" to default to "no". Ensure "wide links = no" if "unix extensions = yes" on a share. Fix man pages to refect this. Remove "within share" checks for a UNIX symlink set - even if widelinks = no. The server will not follow that link anyway. Correct DEBUG message in check_reduced_name() to add missing "\n" so it's really clear when a path is being denied as it's outside the enclosing share path. Jeremy.

2009-09-24vfs catia: Fix the double translation that was happening with createfile and ↵Aravind Srinivasan1-3/+5
open. Since the catia translation is implemented for open, it should not also be done in createfile. By removing createfile from catia, translation is now done correctly for the primary open path. In order to support systems that have custom createfile implementations that don't eventually call SMB_VFS_OPEN, SMB_VFS_TRANSLATE_NAME has been expanded to take an additional argument that specifies direction.

2009-08-28s3: Add a new VFS op called SMB_VFS_TRANSLATE_NAMEAravind Srinivasan1-2/+19
This vop is designed to work in tandem with SMB_VFS_READDIR to allow vfs modules to make modifications to arbitrary filenames before they're consumed by callers. Subsequently the core directory enumeration code in smbd is now changed to free the memory that may be allocated in a module. This vop enables the new version of catia in the following patch.

2009-06-24s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty1-72/+38
This patch introduces two new temporary helper functions vfs_stat_smb_fname and vfs_lstat_smb_fname. They basically allowed me to call the new smb_filename version of stat, while avoiding plumbing it through callers that are still too inconvenient. As the conversion moves along, I will be able to remove callers of this, with the goal being to remove all callers. There was also a bug in create_synthetic_smb_fname_split (also a temporary utility function) that caused it to incorrectly handle filenames with ':'s in them when in posix mode. This is now fixed.
2009-06-10s3: Prepare the first set of SMB_VFS_CREATE_FILE callers to take an ↵Tim Prouty1-8/+18
smb_filename struct Some of the callers required minimal changes, while others (copy_internals) required significant changes. The task is simplified a little bit because we are able to do operations and checks on the base_name when a stream isn't used. This patch should cause no functional changes. Volker, Jeremy: Please check
2009-06-02Add SMB_VFS_CONNECTPATH operationVolker Lendecke1-8/+22
This is required for the shadow_copy2 module and "wide links = no". The file system snapshots by nature are typically outside of share directory. So the REALPATH result fails the wide links = no test.
2009-06-02Remove a variable used just onceVolker Lendecke1-2/+3
2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-14/+14
This patch introduces struct stat_ex { dev_t st_ex_dev; ino_t st_ex_ino; mode_t st_ex_mode; nlink_t st_ex_nlink; uid_t st_ex_uid; gid_t st_ex_gid; dev_t st_ex_rdev; off_t st_ex_size; struct timespec st_ex_atime; struct timespec st_ex_mtime; struct timespec st_ex_ctime; struct timespec st_ex_btime; /* birthtime */ blksize_t st_ex_blksize; blkcnt_t st_ex_blocks; }; typedef struct stat_ex SMB_STRUCT_STAT; It is really large because due to the friendly libc headers playing macro tricks with fields like st_ino, so I renamed them to st_ex_xxx. Why this change? To support birthtime, we already have quite a few #ifdef's at places where it does not really belong. With a stat struct that we control, we can consolidate the nanosecond timestamps and the birthtime deep in the VFS stat calls. At this moment it is triggered by a request to support the birthtime field for GPFS. GPFS does not extend the system level struct stat, but instead has a separate call that gets us the additional information beyond posix. Without being able to do that within the VFS stat calls, that support would have to be scattered around the main smbd code. It will very likely break all the onefs modules, but I think the changes will be reasonably easy to do.

2009-02-19s3: Change the vfs_GetWd cache to use the file_id structTim Prouty1-12/+3
2009-02-09Add an optional SMB_STRUCT_SMB parameter to VFS_OP_READDIRSteven Danneman1-2/+2
* this allows VFS implementations that prefetch stat information on readdir to return it through one VFS call * backwards compatibility is maintained by passing in NULL * if the system readdir doesn't return stat info, the stat struct is set to invalid
2009-02-09s3 oplocks: Make the level2 oplock contention API more granularTim Prouty1-8/+25
This replaces release_level2_oplocks_on_change with contend_level2_oplock_begin/end in order to contend level2 oplocks throughout an operation rather than just at the begining. This is necessary for some kernel oplock implementations, and also lays the groundwork for better correctness in Samba's standard level2 oplock handling. The next step for non-kernel oplocks is to add additional state to the share mode lock struct that prevents any new opens from granting oplocks while a contending operation is in progress. All operations that contend level 2 oplocks are now correctly spanned except for aio and synchronous writes. The two write paths both have non-trivial error paths that need extra care to get right. RAW-OPLOCK and the rest of 'make test' are still passing with this change.
2009-02-09s3 vfs: Add a destructor to the fsp extension data APITim Prouty1-1/+7

2007-12-18Add a in-memory cacheVolker Lendecke1-111/+57
This is a more general API that caches data with a LRU scheme. See include/cache.h. No comments yet, I'm still working on it. But Jeremy has given me a hint in one of his checkins that he would like to make use of this now. The idea is that we get rid of all our silly little caches and merge them all into one cache that we can then very easily trim, for example even with a smbcontrol message if someone decides memory is tight. The main user is the stat cache, this patch also converts the getwd cache. More caches to come. (This used to be commit 7a911b35713538d82001a3c9f34152e293fe1943)

2007-10-30Add new parameter, "min receivefile size" (by default setJeremy Allison1-3/+29
to zero). If non-zero, writeX calls greater than this value will be left in the socket buffer for later handling with recvfile (or userspace equivalent). Definition of recvfile for your system is left as an exercise for the reader (I'm working on getting splice working :-). Jeremy. (This used to be commit 11c03b75ddbcb6e36b231bb40a1773d1c550621c)
2007-10-28Enable vfs objects = /full/path/to/object.soVolker Lendecke1-10/+36
Right now I'm testing a vfs object. I can't right now in make test, because "vfs objects" assumes the .so files to be in $libdir/vfs. This patch parses the module name out of the object name in case it starts with "/". The module name is assumed to be the last path component's basename. (This used to be commit 95cc019af775a6ab28ea602ad767fa54d7c86197)
